Cutting-edge train-signalling system to be tested on Melbourne’s Metro system
Cutting-edge train technology used in Hong Kong could soon be used on the Metro train network and it would change the daily commute in a big way.

New technology that would allow peak-hour trains to run every two minutes on our busiest lines is set to be tested on the network next month.
High-capacity signalling — used in public transport powerhouses, such as Hong Kong — enables trains to wirelessly speak to each other, instead of relying on trackside lights, to allow trains to bunch closer together while ensuring a safe distance.
Signals are being built into tracks and driver cabins of new High Capacity Metro Trains, with a control centre to monitor real-time speed and location data.
The game-changing system would be put into action when the $13.7bn Metro Tunnel opens in 2025, enabling up to 30 trains an hour to travel along the Sunbury, Cranbourne and Pakenham lines.
One HCMT – part of a $2.3bn fleet slowly being added to the network – has now been fitted with the technology and shifted to Epping for Australia-first live testing.
The HCMTs, which started to hit the tracks last year after an 18-month delay, are seven carriages long and can fit 20 per cent more people.
Transport Infrastructure Minister Jacinta Allan said testing would continue for six months before shifting to the Cranbourne and Pakenham lines next year.
“This is an exciting step forward, with the bigger trains meeting the next-generation signalling technology for the first time to test trains and systems ahead of the Metro Tunnel opening in 2025,” she said.
“This generational change in train travel for Melbourne requires a massive testing effort to ensure the new systems can operate safely and effectively before the first passenger steps on to a platform.”
Part of the reason for extensive testing is because the hi-tech system is being fitted to an existing network that also carries freight and country trains. The wireless signalling has been trialled on X’Trapolis trains retrofitted with the technology to ensure safety.
Once rolled out in 2025, it would allow for what has long been talked about for Melbourne’s network – a “turn-up and-go” service. This also requires investments in trains, infrastructure and staff to ensure higher numbers of services can be delivered, which is in the operational budget for the Metro project.
The High Capacity Metro Trains will use high-capacity signalling in the Metro Tunnel and along parts of the Sunbury, Cranbourne and Pakenham lines, but traditional signalling will be used where the new technology is not installed.
